Rail and Air.

Transportation by air has not yet developed to such an extent as to cause grave concern to the rail carrier, but as the years go by the subject of aerial competition will become one of increasing importance to the railway leader. The question of how the aeroplane will fit into railway service if its use should become widespread is full of interest. In this connection it may be noted that the special sub-committee of the Transit Committee of the League of Nations, established for the solution of problems dealing with combined travel by rail and air, has recently reported that there would not appear to be any page 20 insurmountable difficulty in the way of arranging for combined transport by rail and air with a single ticket or bill of lading for the through journey. In Sweden, indeed, co-ordinated rail and air travel is now the order of the day, and is proving of marked convenience to travellers between inland points in Sweden and the great capitals of Europe. The International Railway Union and the International Air Traffic Association are now making further investigation into through rail-air movement, and the results of their inquiry should be helpful alike to the railways and the air carriers in the new transportation era that has opened out with the worldwide development of the aeroplane.
